This is the right hand facing upwards like if your arm was bent at the elbow up towards the sky. The index finger is extended and pointing up. The thumb and the other fingers are curved down into the palm.

This One Finger icon is a responsive icon. This means that it's optimized for four resolutions, from tiny 16x16 until highly detailed 80x80. The style comes from the latest Microsoft Office, which makes it perfect for any Windows applications, in particular, those with ribbon toolbar control. Unlike other icon packs that have merely hundreds of icons, this monster icon pack contains 15,900 icons, all in the same style and quality.
